Abstract (en)
[origin: WO2006094808A2] The invention concerns a method for producing ultrafine suspensions, characterized in that a substance in the form of a solid product at 20 °C is dissolved in a solvent, in that the solvent is very rapidly substantially drawn from said solution, in that the powder thus obtained, whereof the particles have an average particle-size distribution of the order of 1 to 50 µm (by laser diffractometry) is dispersed in a dispersing medium, and in that the resulting suspension is treated subsequently, using average to high forces, so as to obtain a suspension whereof the solid matter particles have a average particle-size distribution (by photon correlation spectroscopy) less than 3 µm, preferably less than 1µm (1000 nm), and in particular less than 400 nm, more particularly still, less than 200 nm.
